Fluoropolymeres - Material Properties
5
Composition and Poperties of PTFE

• Perfluorinated plastic with melting point of 327
  C, molecular weight approx. 108 g/mol
• Complete protection of C-C-bonds by F-atoms
• Processable by pressing, sintering and chip
  removing technics
• Nearly universal resistance to chemicals
• Service temperature - 250 C to 250 C
• High purity, excellent dielectrical properties
• No embrittlement, no aging

6
Composition and Poperties of modified PTFE
TFM-PTFE

• Molecular weight is about 1/5 of the molecular
  weight of PTFE
• Contains the same perfluorinated modifier as PFA,
  but less than 1
• Therefore TFM-PTFE closes the cap between
  classical PTFE and PFA
• Weldable by special technics, thanks to the
  shift versus thermoplastic properties
• Cold-flow, pore content and stretch-void-index
  are improved

7
Composition and Poperties of PFA

• Thermoplastic processable perfluorinated polymere
• Molecular weight approx. 1 of PTFE, therfore
  processable by fusion
• 4 to 10 modifier
• melting point 305 to 290C
• Highly modified ? highly amorph high
  transparency, improved alternate bending and good
  chemical resistance to stress crack
• Chemical stability and service temperature
  comparable with PTFE
• Processing methods injection molding, extrusion,
  transfer molding
• Thermoplastic processing technics open up new
  applications for this material with
  PTFE-properties
